Signal sensor

Abstract

The invention provides a signal sensor. The signal sensor comprises a housing, having a connector and a display unit; a tuner, configured to receive a cable signal; a microcontroller unit (MCU), electrically connected with the tuner and the display unit; a scanning switch, electrically connected with the MCU; a power supply, configured to supply a power to the MCU, the tuner and the white LED; and a power switch, electrically connected with the MCU.

The invention claimed is: 
     
       1. A signal sensor, comprising:
 a housing, which includes a connector and a display unit mounted thereon; 
 a tuner, arranged in the housing and configured to receive a signal; 
 a microcontroller unit (MCU), arranged in the housing and electrically connected with the tuner and the display unit; 
 a scanning switch, arranged in the housing and electrically connected with the MCU; 
 a power supply, configured to supply a power to the MCU, the tuner and a white LED; and 
 a power switch, electrically connected with the MCU; 
 wherein the signal sensor determines whether the signal belongs to a coaxial cable signal according to signal intensity of the signal. 
 
     
     
       2. The signal sensor of  claim 1 , wherein the power supply is implemented as a dry battery socket or a USB port. 
     
     
       3. The signal sensor of  claim 1 , wherein the display unit is an LED light. 
     
     
       4. The signal sensor of  claim 1 , wherein the connector is an F-type male connector. 
     
     
       5. The signal sensor of  claim 4 , wherein the F-type male connector is a 75 Ohm F-type male connector. 
     
     
       6. The signal sensor of  claim 1 , wherein the tuner scans the signal within a frequency range. 
     
     
       7. The signal sensor of  claim 6 , wherein the frequency range is from 88 MHz to 1 GHz. 
     
     
       8. The signal sensor of  claim 6 , wherein the tuner scans the signal based on a scanning bandwidth. 
     
     
       9. The signal sensor of  claim 6 , wherein the scanning bandwidth is 6 MHz.
